IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed in New York, New York.

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture (For Unsecured Debt Securities), dated as of November 1, 2017 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, including the Board Resolutions and Officer’s Certificate filed with the Trustee on November 6, 2017, creating the series designated on the face hereof (herein called the “Officer’s Certificate”), for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities of this series and of the terms upon which the Securities of this series are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof.

The Securities of this series shall bear interest at a variable rate per annum (the “Interest Rate”) equal to the Three‑Month LIBOR Rate (as defined below), plus 28 basis points (0.28%). The Interest Rate for the period from November 6, 2017, the date of original issuance, to the first Interest Payment Date was determined on November 2, 2017. The Interest Rate on the Securities of this series for each subsequent Interest Period will be reset quarterly on the related LIBOR Rate Reset Date (as defined below).

If an Interest Payment Date, other than a Redemption Date or the Stated Maturity Date of the Securities of this series, falls on a day that is not a Business Day, the Interest Payment Date will be postponed to the next day that is a Business Day (and without any interest or other payment in respect of such delay) with the same force and effect as if made on the Interest Payment Date, except that if such next Business Day occurs in the next succeeding calendar month, the Interest Payment Date will be the immediately preceding Business Day. If a Redemption Date or the Stated Maturity Date of the Securities of this series falls on a day that is not a Business Day, then payment of the interest or principal payable on such Redemption Date or Stated Maturity Date will be made on the next succeeding day which is a Business Day (and no interest will be paid or other payment made in respect of such delay), and no interest on such payment will accrue for the period from and after such Redemption Date or the Stated Maturity Date, as applicable. If any LIBOR Rate Reset Date falls on a day that is not a LIBOR Business Day (as defined below), the LIBOR Rate Reset Date will be postponed to the next day that is a LIBOR Business Day, except that if such next LIBOR Business Day occurs in the next succeeding calendar month, the LIBOR Rate Reset Date will be the immediately preceding LIBOR Business Day. The Interest Rate in effect on any LIBOR Rate Reset Date will be the applicable rate as reset on such LIBOR Rate Reset Date and the Interest Rate applicable to any other day will be the Interest Rate as reset on the immediately preceding LIBOR Rate Reset Date. The provisions of this paragraph shall supersede the provisions of Section 113 of the Indenture to the extent the provisions are inconsistent.

“Calculation Agent” means a banking institution or trust company appointed by the Company to act as calculation agent, initially The Bank of New York Mellon.

“LIBOR Business Day” means any day on which dealings in deposits in United States Dollars are transacted in the London Inter‑Bank Market.

“LIBOR Interest Determination Date” means (i) the second LIBOR Business Day preceding each LIBOR Rate Reset Date or (ii) November 2, 2017, in the case of the initial Interest Period.

“LIBOR Rate Reset Date” means, subject to the paragraph immediately preceding the definition of “Calculation Agent” set forth above, the 6th day of February, May, August and November of each year continuing until Maturity, commencing on February 6, 2018.

“Three‑Month LIBOR Rate” means the rate determined in accordance with the following provisions:

(1)    On the related LIBOR Interest Determination Date, the Calculation Agent will determine the Three‑Month LIBOR Rate, which will be the rate for deposits in United States Dollars having an index maturity of three months which appears on the Bloomberg L.P. page “BBAM” or on such other page as may replace the Bloomberg L.P. page “BBAM” on that service, or, if on such LIBOR Interest Determination Date, the Three‑Month LIBOR does not appear or is not available on the designated Bloomberg L.P. page “BBAM,” Reuters Page LIBOR01 (or such other page as may replace the Reuters Page LIBOR01 on that service) as of 11:00 a.m., London time, on the LIBOR Interest Determination Date.

(2)    If no rate appears on either the Bloomberg L.P. page “BBAM” or the Reuters Page LIBOR01 on the LIBOR Interest Determination Date, the Calculation Agent will request the principal London offices of four major reference banks in the London Inter‑Bank Market (“Reference Banks”) selected by the Company to provide it with their offered quotations for deposits in United States Dollars for the period of three months, commencing on the applicable LIBOR Rate Reset Date, to prime banks in the London Inter‑Bank Market at approximately 11:00 a.m., London time, on that LIBOR Interest Determination Date and in a principal amount of not less than $1,000,000. If at least two quotations are provided, then the Three‑Month LIBOR Rate will be the average (rounded, if necessary, to the nearest one hundredth (0.01) of a percent) of those quotations. If fewer than two quotations are provided, then the Three‑Month LIBOR Rate will be the average (rounded, if necessary, to the nearest one hundredth (0.01) of a percent) of the rates quoted at approximately 11:00 a.m., New York City time, on the LIBOR Interest Determination Date by three major banks in New York City selected by the Company (“Major Banks”) for loans in United States Dollars to leading European banks, having a three‑month maturity and in a principal amount of not less than $1,000,000. If the banks selected by the Company are not providing quotations in the manner described by this paragraph, the rate for the quarterly interest period following the LIBOR Interest Determination Date will be the rate already in effect on that LIBOR Interest Determination Date.

The Interest Rate for any Interest Period will at no time be higher than the maximum rate then permitted by applicable law.

All percentages resulting from any calculation of the Interest Rate will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 3.876545% (or .03876545) being rounded to 3.87655% (or .0387655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

Absent willful misconduct, bad faith or manifest error, the Calculation Agent’s determination of the Three-Month LIBOR Rate and its calculation of the applicable Interest Rate for each Interest Period will be final and binding on the Company, the Trustee, the Calculation Agent and Holders of the Securities of this series. The Holders of the Securities of this series may obtain the Interest Rate for the current and preceding Interest Periods by writing the Calculation Agent at The Bank of New York Mellon, Attn: Corporate Trust Administration, 101 Barclay Street, New York, New York 10286, or any successor appointed by the Company.

The Calculation Agent shall, as soon as practicable after 11:00 a.m., London time, on each LIBOR Interest Determination Date, determine the Interest Rate and the Company will calculate the amount of interest payable on the Securities of this series in respect of the applicable Interest Period (the “Interest Amount”). The Interest Amount shall be calculated by multiplying the Interest Rate for that Interest Period by a fraction, the numerator of which will be the actual number of days elapsed during such Interest Period (determined by including the first day of the Interest Period and excluding the last day), and the denominator of which will be 360, and by multiplying the result by the aggregate principal amount of the Securities of this series. The determination of the Interest Amount by the Company will (in the absence of willful misconduct, bad faith or manifest error) be final, conclusive and binding on all concerned. None of the Trustee, the Calculation Agent or the Company (or any of their respective officers, directors, agents, beneficiaries, employees or affiliates) shall have any liability to any Person for (i) the selection of the Reference Banks or the Major Banks or (ii) failure of the Reference Banks or the Major Banks to provide quotations to the Calculation Agent. Promptly upon the determination of the Interest Rate and the calculation of the Interest Amount, the Calculation Agent and the Company, respectively, will notify the Trustee of such Interest Rate and Interest Amount.

The Securities of this series shall be redeemable at the option of the Company in whole or in part at any time or from time to time on or after May 6, 2018 (each a “Redemption Date”), upon notice (the “Redemption Notice”) mailed at least ten (10) days but not more than sixty (60) days prior to the Redemption Date at the price (the “Redemption Price”) equal to 100% of the principal amount of the Securities of this series being redeemed plus accrued and unpaid interest, if any, on the Securities of this series being redeemed, to but excluding the Redemption Date.

If at the time the Redemption Notice is given, the redemption moneys are not on deposit with the Trustee, then, if such notice so provides, the redemption shall be subject to the receipt of the redemption moneys on or before the Redemption Date and such Redemption Notice shall be of no force or effect unless such moneys are received.

Upon payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions set forth in the Indenture, including the Officer’s Certificate described above.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of and interest on the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected by such amendment to the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be thus affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by Holders of the specified percentages in principal amount of the Securities of this series shall be conclusive and binding upon all current and future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and shall have failed to institute any such proceeding, for sixty (60) days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and integral multiples thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor and of authorized denominations, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the absolute owner hereof for all purposes, whether or not this Security be overdue, and none of the Company, the Trustee or any such agent shall be affected by notice to the contrary.
